The invention discloses an intelligent lighting control method or device with a real-time clock, which solves the defects that the traditional lighting controller can control light and waste electric energy only by issuing a control command again by an integrated controller after being electrified. Especially, after the centralized controller has issued a related light-off or dimming command and suddenly cuts off power and then powers on again, all lights return to the conditions of full-on and 100% light intensity again, and the requirement of energy conservation cannot be met.
Meanwhile, the traditional controller cannot perform local communication with the lighting controller under the influence of the environment, at the moment, the centralized controller cannot transmit a control command to the lighting controller in real time, the lighting controller cannot perform the operations of turning off and dimming the lamp bulb, the effect of energy conservation and emission reduction cannot be achieved, meanwhile, related faults of the lighting lamp cannot give an alarm in real time, and the safety is influenced.
Because the RTC real-time clock circuit and the EEPROM store the illumination strategy issued by the concentrator before, the invention can automatically carry out on-off control and dimming control of light according to the stored illumination strategy and the real-time clock under the condition that the controller can not be communicated with the centralized controller, thereby achieving the effects of energy saving and emission reduction and achieving the technical effect of saving electric energy.
Meanwhile, the illumination controller of the invention can also receive and make a new illumination strategy issued by the centralized controller in real time, after receiving the new illumination strategy issued by the centralized controller, the MCU of the controller can compare the new illumination strategy with the illumination strategy stored in the local EEPROM, if the new illumination strategy is different, the MCU updates the new illumination strategy, and if the new illumination strategy is the same, no operation is made.
When the specific implementation is carried out, when the time that the lamp needs to be turned on is reached every day, the integrated controller turns on all the light through line control, and when the lamp needs to be turned off, the integrated controller turns off all the light through line control; when a certain bulb needs to be turned off or dimmed at a specific time in the morning, the centralized controller issues a control command to the lighting controller through power line carrier communication, after a communication module of the lighting controller receives the control command, the control command is transmitted to the MCU, the MCU disconnects the 220V power supply of the operation relay according to the type of the control command if the control command is the light-off command, the light is turned off, and outputs a dimming circuit for adjusting 0-10V or PWM if the control command is a dimming signal. The simultaneous control ware can automatic measurement bulb's measurement data (like electric current, voltage, active power, idle work, power factor etc.) and power-on time, when the centralized control ware needs to read, transmit this data to the centralized control ware through communication module, the state signal of simultaneous control ware ability automatic recording controller, under the condition that takes place unusually, can report the centralized control ware with abnormal state initiative in real time, let managers can know the state of bulb, in time handle the trouble.
The invention well solves the problem that the illumination controller automatically controls the controller according to the stored illumination strategy under the condition that the illumination controller cannot establish communication with the concentrator controller, thereby achieving the effects of energy conservation and emission reduction, and compared with the traditional controller, the energy-saving effect exceeds 10 percent.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
